Product Engineer

At 8returns, we're transforming one of the most frustrating, environmentally damaging and costly aspects of e-commerce: returns.

Trusted by the fastest-growing DTC names like OACE, PEGADOR, GOT BAG and now adopted by iconic brands such as Fielmann, Tommy Hilfiger, and Reebok, we're inventing what's next in post-purchase.
